NIS JOHNSON, OF MERIDEN, CONNECTICUT, ASSIGNOR TO THE MERIDEN BRONZECOMPANY, OF SAME PLACE.

FILLING-INDICATOR.

SPECIFICATION forming part of Letters Patent No. 509,170, dated November21, 1893.

Serial No.'482,139. (No model.)

To all whom it may concern:

Be it known that I, NIS JOHNSON, of Meriden, in the county of New Havenand State of Connecticut, have invented a new Improvement inFilling-Indicators for the Founts of Oil-Burning Lamps; and I do herebydeclare the following, when taken in connection with accompanyingdrawings and the letters of reference marked thereon, to be a full,clear, and exact description of the same, and which said drawingsconstitute part of this specification, and represent, in-

Figure 1, a broken view in vertical section of a lampfount provided witha filling-indicator constructed in accordance with my invention; Fig. 2,a detached plan view of the nipple with its cap removed. Y

Myinvention relates to an improvernentin lling-indicators for the fountsof oil-burning lamps, the object being to produce a simple, cheap andeffective device.

With these ends in View, my invention consists in a filling indicatorhaving certain details of construction as will behereinafter describedand pointed out in the claim.

In carrying out my invention, I attach a depending bracket A, directlyto the lower end of a filling nipple B, 'which is otherwise of ordinaryconstruction, and adapted to be secured within an opening formed in thetop of a lamp-fount C, and to receive a filler cap D. The said bracketA, may, it' desired, be made integral with the nipple, but it willprobably be found best to make it independent thereof, and attach itrigidly thereto. The lower end of the bracketisturned inward at a rightangle, and constructed with a circular opening a, adapting it to receivea tube E, the upper end of which is expanded, as at e, for thesuspension of the tubein the bracket.

The said tube E, containsv a ioat, preferably 1n the form of an invertedtube E, made of aluminum, or some correspondingly light material, andadapted in diameter so as to move freely up and down in the tube E, thelower end of which is closed slightly, as at e', to hold the Iioat-tubeF in place against downward displacement.

It will be understood that when the fount is being filled, and as theoil rises therein, the float F, will rise in the tube E, and indicatethe rise of oil in the fount. By attaching the bracket directly to, orforming it integral with the nipple, I secure a very simpleconstruction, and one notliable to derangement, while by arranging thetube E, and its float in a vertical plane, the device operates with theminimum of friction, Whereas when the float is arranged to operateotherwise, it may stick, or be retarded, and fail to give its rightindication..

, I would have it understood that I do not I broadly claim thecombination with a filling nipple, of a bracket and two tubes, but onlymy particular construction.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

The combination with a nipple adapted to be inserted int-o the top of alamp-fount, of a bracket rigidly connected therewith and dependingtherefrom, and turned inward at a right angle at its lower end, avertically arranged tube depending from the said lower end of thebracket, and a vertically movable iioat located in the said tube,substantially ascand for the purpose set forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.

NIS JOHNSON.
